Magnetic and optical properties of polycarbonate/Fe nanocomposites

摘要

The magnetic and optical properties of poly-carbonate (PC)/Fe nanocomposite films prepared by a solution blended process and the role of Fe additives are investigated. The saturation magnetization of the PC/Fe nanocomposites depends on the weight of Fe nanoparti-cles. Meanwhile, an increase of photoluminescence (PL) intensity with decreasing Fe additives is interpreted. The optical band gap corresponds to the increase of PL ele-ments. The transmittance of the films increases with reduced Fe, and the PL peak energy of PC/Fe composites is also correlated to the weight ratio.
